Robert's Review of the Cold Drip Coffee Maker
I'm impressed. This is a beautiful coffee maker and it makes a very smooth cup of coffee. It stands about 23" tall and reminds me of an instrument you'd find in a chemistry lab. (I'm also attracted to vacuum pots for the same look.)
I have made two pots of coffee so far. The instructions said the result would be a concentrate that should be diluted to make a cup of coffee. On the first batch, using Sumatra Mandheling, I followed the instructions carefully. I loaded up the top beaker with ice, measured the exact amount of coffee (7 tablespoons) per the instructions, arranged the filters just right, added a little water to get it started, and adjusted the valve to deliver about a drop per second. It comes with a supply of paper filters and a cloth filter that is similar to the ones used in vac pots. It took about eight hours to finish melting and brewing. The coffee was not a concentrate but tasted very good after a minute in the microwave. The coffee was very smooth and mellow. I liked it. My wife liked it.
I then put the carafe in the refrigerator and tried it again after one week. Still good, better than most restaurant coffee, but not as good as before. In addition to making a great cup of hot coffee, it would be a good brew for freezing and then using in an iced coffee drink.
On my second batch, I used Ethiopian Yirgacheffe and changed the formula slightly. I wanted to make a coffee concentrate so I used 70 grams of coffee, with the same amount of ice. As you can see in the photo (just below the valve), I almost filled the cup with coffee grounds. This time I produced a concentrate. I diluted it two parts water to one part concentrate. I tried it cold and it was very good. I then heated it in the microwave and had a very good cup of coffee. Smooth and mellow. It had none of the "bite" you usually find in Yirgacheffe.
This lack of acidity and bitter taste appeals to many. The cold water coffee extraction makes a different tasting coffee because many of the harsh acids and oils never make it to the cup, as in the hot water process. I like the idea of having some coffee concentrate in the refrigerator or freezer for that quick cup or glass of coffee.
This coffee maker sells for $99 and is available from Coffee-Snob.com.
